How to Build an Outdoor Fireplace with Pavers

An outdoor fireplace can be a beautiful and functional addition to any backyard. It provides a cozy gathering spot for friends and family, and it can extend the enjoyment of your outdoor space into cooler weather. While a custom-built fireplace can be expensive, building your own fireplace using pavers is a more affordable and achievable option. This guide will provide detailed steps on how to build an outdoor fireplace with pavers, ensuring a safe and enjoyable experience.

1. Planning and Preparation

The first step in building an outdoor fireplace is planning and gathering the necessary materials.

1.1 Determine the Location:

Choose a location that is away from flammable structures and overhangs. Ensure adequate clearance around the fireplace for safety.

1.2 Choose a Design:

Decide on the shape and size of your fireplace. Consider factors like the space available, the desired aesthetic, and the number of people who will be using it. You can choose a single-sided design, a corner fireplace, or even a more elaborate design with a built-in seating area.

1.3 Obtain Necessary Permits:

Check with your local building department for any required permits. This step helps ensure your fireplace meets local building codes and safety regulations.

1.4 Gather Materials:

The specific materials needed will depend on your chosen design, but common materials include:

Pavers (consider fire-resistant options)
Gravel or sand for the base
Firebrick for the firebox
Mortar mix
Rebar or steel mesh for reinforcement
Chimney pipe and cap
Fire grate or grate kit
Level, tape measure, and other tools

2. Excavation and Foundation

Once your plans are in place, you can begin building the foundation for your fireplace.

2.1 Excavate the Area:

Carefully dig a hole for the fireplace base, making sure it is large enough to accommodate the design. The depth should be at least six inches to provide a solid base.

2.2 Prepare the Base:

Level the excavated area and compact the soil. Lay down a layer of gravel or sand for drainage and stability. You can use a tamper to compact the gravel layer.

2.3 Build the Foundation:

Create a concrete foundation for the fireplace. Mix concrete according to the manufacturer's instructions and pour it into the prepared base. Use a level to ensure even surfaces and allow the concrete to cure completely.

2.4 Install Firebrick:

After the concrete cures, lay firebrick around the perimeter of the firebox to create a safety barrier. You can use mortar mix to secure the firebricks, ensuring a tight seal against the concrete base.

3. Building the Fireplace Structure

With the foundation in place, you can start building the exterior structure of the fireplace.

3.1 Lay the First Course of Pavers:

Begin laying the pavers on the foundation, starting with the bottom course around the firebox. Use a mortar mix to bind the pavers together and ensure a secure structure.

3.2 Reinforce with Rebar or Mesh:

If you have chosen a tall fireplace design, use rebar or steel mesh between courses of pavers to provide additional strength. This step is crucial for stability, especially with taller structures.

3.3 Continue Laying Pavers:

Continue laying pavers in courses, using mortar mix to bond them securely. Ensure the pavers are level and aligned to create a visually appealing and stable structure.

3.4 Build the Mantle:

If you are incorporating a mantle into the design, create a support system for it using pavers and mortar. Ensure it is properly secured and can comfortably hold the weight of the mantle.

4. Installing the Chimney

A chimney is essential for venting smoke and gases from the fireplace.

4.1 Choose Chimney Pipe:

Select chimney pipe made of a fire-resistant material, such as stainless steel or clay. Ensure the diameter of the pipe aligns with the size of the fireplace opening.
